Development of glyphosate resistant transgenes started in the early 1980s and was commercially introduced in soybean varieties in 1996 as Roundup Ready?(hereafter referred to as RR1) (SourceWatch, 2012). Producers perceived that the more effective, easier, and less expensive weed control associated with these varieties outweighed the economic loss from lower yields (Gurian-Sherman, 2009). In 2008, the Roundup Ready 2 Yield varieties were commercialized as Genuity?Roundup Ready 2 Yield?(hereafter referred to as RR2Y) in 2010 (SourceWatch, 2012). RR2Y soybean varieties have been rapidly replacing the RR1 varieties in the marketplace.
